HV623 32-Channel 128-Level Amplitude Gray-Shade Display Column Driver

The HV623 is a 32-channel driver IC for gray shade display use. It is designed to produce varying output voltages between 3 and 80 volts. This amplitude modulation at the output is facilitated by an external ramp voltage VR. See Theory of Operation for detailed explanation. This device consists of a.
